Many people have heard of assisted reproductive technologies but often confuse "in vitro fertilization" (IVF) with "artificial insemination." In reality, third-generation IVF (IVF-PGT) and traditional artificial insemination differ significantly in their technical principles and applicable scope.

 

First, let's clarify what IVF is. It does not literally involve fertilizing a baby in a test tube but rather is an assisted reproductive technology where mature eggs are retrieved from a woman's ovaries and fertilized with optimized sperm in a specialized culture medium. The resulting embryos are then cultured in a laboratory dish to a certain stage (usually the 4-8 cell cleavage stage or the blastocyst stage) before being transferred back to the mother's uterus for implantation and pregnancy. To increase the success rate, ovulation induction is usually performed before egg retrieval to obtain multiple mature eggs.

 

Artificial insemination (intrauterine insemination, IUI) is a relatively simple assisted reproductive technique. It involves the medical introduction of processed semen from a male directly into the cervix or uterine cavity around the time of a woman's ovulation to shorten the distance sperm have to travel to the egg, thereby increasing the chances of natural fertilization. Depending on the specific situation, multiple inseminations can be performed within a single ovulation cycle. Unlike IVF, the fertilization process in artificial insemination still occurs inside the woman's body.

 

Regarding embryo transfer, IVF allows for the selection of fresh or frozen embryos for transfer, while artificial insemination uses either fresh or refrigerated semen. With advancements in assisted reproductive technology, both embryos and semen can be cryopreserved for extended periods, allowing for thawing and use at an appropriate time. This technology offers more options for families planning egg freezing in Mexico for future use.

 

Understanding the differences between third-generation IVF (IVF-PGT) and artificial insemination is crucial for families hoping to achieve their reproductive dreams through assisted reproductive technologies. IVF-PGT, as the core of third-generation IVF, builds upon traditional IVF by adding preimplantation genetic testing (PGT). This allows for the screening of embryos for chromosomal number and structural abnormalities, excluding abnormal embryos and thus increasing the embryo implantation rate and reducing the risk of miscarriage. This is a significant advantage, especially for older couples or those with a history of genetic diseases, which artificial insemination does not offer.
